Powers/Abilities: Stardust appears to be composed of
cosmic energy. Though he can be struck, pained, and even torn to pieces, he can
reform at will. It is unknown whether he can truly be destroyed. He sometimes
focuses his energy blasts through a staff with an axe-like blade at one end and a curved
spear at the other, but he can project blasts from his hands or face as well. He
can open portals into other dimensions. He
can survive unaided in the vacuum of space and presumably does not need air,
food, water, etc. He likely is immune to aging and conventional disease.

He possesses a large dorsal fin-like mane,
a long tail, a digitigrade stance (with two toes), and his arms are divided into
two portions proximal to the carpus (see comments). It would seem that he has
three rows of eyes.

History:
(Annihilation: Heralds of Galactus#1/2 (fb) - BTS) -
Some of the first particles in Universe-616 formed a noncorporeal
civilization, the Ethereals, into which the future Stardust was born

(Stormbreaker: The Saga of Beta Ray Bill#3 (fb) - BTS) -
Stardust (by his own account) has "seen valleys fill with water and become
rivers," "seen water wear away rocks to create valleys," "seen earth smash
together with such force that it raises into the sky to become mountains," and
"seen the face of god and torn away his mask."

(Stormbreaker: The Saga of Beta Ray Bill#1) - Beta Ray Bill
arrived to find New Korbin devastated and assaulted Galactus (unaware of his
true nature, as he appeared in the non-human form of Ashta to Korbinites).
Galactus summoned Stardust to destroy Beta Ray Bill, and the two battled, with
Bill trying to delay the pair so that the remainder of the Korbinite fleet could
escape. Firing energy blasts at each other, they reached a stalemate, until
Galactus swatted and incapacitated Bill.

(Stormbreaker: The Saga of Beta Ray Bill#2) - Stardust gained
Galactus' permission to hunt down and exterminate the remainder of the Korbinite
fleet to destroy all remnants of their civilization to serve as an example of
those who would resist Galactus. As he easily overpowered all he found, he came
across the incapacitated Alpha Ray, precursor to Beta Ray Bill. Stardust brought
Alpha Ray back to Galactus to slay him in Galactus' presence, but Galactus
instructed him to stay his hand as Alpha Ray had fought against Beta Ray Bill.
Upon realizing that Beta Ray Bill had cracked Galactus' armor, Stardust went
after Bill, intending to fill the rent with Bill's body. As he approached Bill
aboard his starship, Skuttlebutt, he obtained the Meta-Orb, which contained the
life forces of those not slain in the recent attacks. Stardust contacted Bill,
telling him to come to him and he might spare his people. Bill confronted him as
desired.

(Stormbreaker: The Saga of Beta Ray Bill#3) - Bill snatched
the Orb from Stardusts hands, sending it aboard Skuttlebutt, whom he instructed
to escape. Stardust admitted to having underestimated Bill, but then bragged of
his own experiences and attacked Bill with great power. Remarking on his own
experience and the Odinpower, Bill blasted Stardust, tackled him into a
planetoid which was destroyed by the impact, and then seemingly dispersed his
energy form with a blow from his hammer, Stormbreaker. Stardust reformed,
admitted to being impressed, and vowed to crush Bill. The two fought savagely,
but as Bill withstood the assaults and hurt Stardust again with Stormbreaker,
Stardust opened a dimensional warp into a cosmic Hell into which he intended to
cast Bill. A massive tendril lashed out of the portal and latched onto Bill, who
severed it from its attachment. Realizing that something from the Hell had now
escaped the portal, Stardust closed the portal and the blasted the severed dark
matter as it began to coalesce into human form. Unharmed, it blasted Stardust
and Bill into submission, took a feminine semi-humanoid form, and named itself
Asteroth.

(Stormbreaker: The Saga of Beta Ray Bill#4) - Stardust
recovered from the blast and revived Bill, hoping to join forces with him
against Asteroth, but Bill attacked him savagely, tearing off Stardust's hand
with his teeth. Stardust finally managed to convince Bill that Asteroth was the
greater danger and must be stopped before she could acclimate to the physical
universe and become too powerful. Stardust and Bill slammed into Asteroth,
smashing her into the core of a planet, but she then obliterated the entire
planet, emerging unharmed. Feeling he had no choice, Stardust opened a black
hole behind Asteroth, but she resisted its gravity well and instead redirected
it at Stardust and Bill, who were pulled into the event horizon towards certain
death.

(Stormbreaker: The Saga of Beta Ray Bill#5) - Stardust and
Bill drifted into Asteroth, who attacked them both. They fought her, trying to
trap her in the event horizon, at which point she sensed the approach of Alpha
Ray, empowered by Galactus to oppose her. Stardust blasted Asteroth, distracting
her, and then Alpha Ray slammed into her, knocking her close enough to the black
hole that they were both pulled into it. Stardust was apparently pulled into the
black hole as well, while Bill had been knocked away from it by Alpha Ray's
impact. The Black Hole then closed.

(Annihilation: Silver Surfer#3) - Stardust appeared before
Firelord, Red Shift, and the Silver Surfer, taking the Surfer's place alongside
the others in exchange for the Surfer heeding the summons. As soon as the Surfer
departed, several ships of the Annihilation Wave arrived to attack them. The
three heralds fought back fiercely

(Annihilation#1) - Red Shift, Stardust and Firelord fought in the orbit of Daedalus 5 the forces of the Annihilation Wave.

(Annihilation#2) - Red Shift and Stardust were called by Peter Quill down to the surface of Daedalus 5 to help against the Annihilation Wave forces led by Ravenous.

(Annihilation#3) - Stardust and Red Shift cleared a path to the emergency ships to give their allies the chance to escape. When Annihilus activated Galactus, who Thanos had turned into a weapon for him, Red Shift and Stardust bought their allies enough time to escape by blocking the attack for a few seconds.

(Annihilation: Heralds of Galactus#1/2) - Stardust rebuilt himself and was drawn to the Andromeda Galaxy by the Power Cosmic. He encountered members of his race and learned that they were the last survivors after the Annihilation Wave's attack. They accused Stardust of being a traitor because he fought along the corporeals and attacked him. Stardust destroyed the group and absorbed what was left of them. After that he returned to his master Galactus, who wasn't surprised to see Stardust alive. Stardust asked to be Galactus' herald again, but Galactus denied his wish because the Silver Surfer was now his herald again. Stardust then proofed his loyalty by giving Galactus the energies of the last Ethereals and Galactus decided that it was time for him to have two heralds at once. Stardust then began to search for worlds Galactus
could devour, noting that she loved Galactus.

(Fantastic Four#545-546) - Stardust aided the Silver Surfer
against the Fantastic Four and Gravity, but was overpowered by Gravity (briefly
empowered as the Protector of the Universe) and the Human Torch (who had
received the power cosmic, stolen from the Surfer by the Black Panther via
Doom-derived technology). Gravity eventually sacrificed his own cosmic power to
temporarily sate Galactus so that he did not have to feed on Epoch, after which
Galactus restored the Surfer and Stardust's power and then left in peace.

I'm not sure Stardust actually is a "he," but I used "he" and
"him" in the profile for ease of description.
More recent stories are referring to Stardust as a female.

I THOUGHT that division of the limb into two parts starting
proximal to the carpus (wrist) was syndactyly, but that is actually fusion of
the digits into a lesser number of separate digits. I can't remember the real
name for it.
